Gearbrake and trailer

Will the Gearbrake activate the trailer lights the same way. Looks like a great product.

Would think if it activates the bikes lights; then when trailer attached would carry right through to the trailer also.

My brake modulator does on my time out trailer.

But I tapped into the wiring @ the brake lite switch.

I sure hope so! I didn't even think about that when I installed mine.
Guess I'll find out next time I hook up the trailer...

It simply plugged into the harness under the seat, right? If so that's where the trailer module plugs in, if you have the BRP hitch and module. So, it'll activate the trailer lights if you plugged it in ahead of the trailer module but not if you plugged it in after the BRP module Y harness.
 
Have to agree...

:agree: but would suspect that they will work for both. They all operate off the same sending switches....

Does not matter where you plug it in, before or after the harness. It will activate the trailer lights. There is no diode to stop the backfeed, is there?

I'm sure the Gearbrake will handle the trailer lights OK but it needs to be plugged in ahead of the trailer module Y harness.

The Y harness is a tap into the wires going to the rear lights so they get their power from the sending switches. Anything downstream of the Y has no affect on what is connected to the Y. My brake light modulator does not affect my trailer lights. The Y harness is down stream of the sending switches.

OK, so check this out, I had Spyderpops put on the bumpskid with leds. Its tied into the fender lights on the right front wheel. I put the Gear brake on yesterday and last night when I step on my brake to crank it the leds on the bumpskid come on.....?????:banghead:

Any ideas why ?

You sure the bumpskid lights are not coming on as soon as you turn the key on? The fender lights do, or at least they're supposed to. Did you use the plugin version of the Gearbrake, or did you splice it into the wires yourself? If the latter you probably connected it to the wrong wire. The tail lights and license plate light are on the same circuit from the fuse as the fender lights. If it was the plugin version they crossed up some pins in the connectors.

The Gearbrake connects only to the brake lights, right? It doesn't connect to the taillights, or at least I don't think it should. I'm not familiar with it.

I should have looked at the wiring diagram for the gear brake before commenting. :opps: It's not a feed in circuit. It's spliced into the circuit.
 
It is plugged in, I didn't cut anything ...and yes the key is off, I first noticed it in my garage when I hit the brakes to show her the new flasher...and the LEDS came on in front...weird.
 
If I remember right, you're missing a diode. The diode allows the current to run in one direction only. When you press the brake and other lights light, that says you have current running in both directions. That happened to me once.

The Gearbrake module is supposed to affect the brake lights only, correct? I think you need to contact Gearbrake. There is something screwed up in their connector configuration. The connector you plugged it into has a wire going to the license plate light. That light is on the same circuit as the fender lights. The harness is cross wired someway so that the brake signal is also being fed into the license plate light wire, thus causing the fender lights and bumpskid LEDs to light up. Check to see if the license plate light comes on when you press on the brake, with the key off. I'll bet it does.

I have to disagree with Copperman about the diode. There's no need for a diode and the two circuits that are involved in your problem are not connected in any way downstream of the brake light switch. In fact, the brake lights are one of the few circuits on the Spyder where the switch is in the 12 volt power side of a load. Most of the switches break the ground side, not the power side, such as the horn.

Yes, my license plate light and all the running lights light as long as I hold the brake. They don't flash like the brake, and go off as soon as I release. Gearbrake doesn't seem to know why either. This is his email to me.

"What is happening is with the fuse on the acc line to keep it hot all the time.
We tap into that circuit to power the module. If you look at our module there are 4 wires. 1 is Ground, 1 is Brake Input, 1 is Brake Output, and 1 is 12V constant. We tap into the 12V constant to power the module. This is usually the running light circuit, but on bikes that have an accessory circuit we tap into it. They are usually switched power so they turn off when the bike turns off.

This does mean that the module will be powered constantly as well, which will theoretically reduce the life of the module somewhat, but since it is solid state electronics it will last years. You could also add a switch to the module input power to be able to turn it on or off as well if you need to".

I told him that I had changed my fuse to make the acc hot all the time, but when I take the fuse back to key off....it still does it, doesn't change a thing.

He says it shouldn't hurt anything...I hope not...

Obviously what's happening is there is a cross feed inside the Gearbrake module or a trigger voltage that activates a transistor in the constant power feed inside the module. When you press the brake the voltage from the brake circuit is turning on and getting a path to the constant voltage line, thus powering up the constant voltage line. He's right, it probably won't hurt anything, but it is piss poor electronic design. So in one respect Copperman is right, there is a diode missing, but it's missing inside the Gearbrake module. Or, you have an incorrectly manufactured module, but I would bet on the improper design. I no longer suspect anything incorrect in the wiring harness connections.

Feel free to send them my comment here. In fact, since you've already had an email exchange with them I'd like for you to do that.

Gearbrake and CANBUS

I was just looking at this item as a possible addition to both my 2016 RT and my husband's Indian Roadmaster. Plain as day on their website is a statement that ..."this module will not work on CANBUS and newer bikes such as BMW and Ducati."

Might this be the problem? That GearBrake is not compatible with the CANBUS on the Spyder (if so, it probably won't work on the Indian either, as it also uses a CANBUS system).

Please keep us posted on what you find .... Ann
